Ukraine denies any involvement in Trump-Putin relationship and dismisses concerns about U.S. election interference.

• According to Ukraine's Foreign Minister Dmytro Kuleba, who spoke to CNBC, there is no possibility for Putin and Trump to reach an agreement on something concerning Ukraine if Trump becomes president.
• President Zelenskyy received "encouraging" messages from political and business leaders at Davos, according to what he said.

Dmytro Kuleba, Ukraine's Foreign Minister, stated on CNBC Thursday that he believes there won't be a significant change in support for his country if Donald Trump is re-elected as the U.S. president later this year.

Kuleba stated: "I don't believe there is a potential for Putin and Trump to agree on something behind Ukraine's back if Trump becomes president."

He stated to CNBC's Steve Sedgwick at the World Economic Forum in Davos that it's not just him thinking out loud, but the reality that dictates the understanding of the dynamics regarding Ukraine's ongoing war with Russia.

Trump's approval of sanctions on Nord Stream 2 and his role as the first to sell lethal weapons to Ukraine were mentioned by Kuleba.

Ukraine's President Volodymyr Zelenskyy stated at Davos on Tuesday that in his belief, one man cannot alter an entire nation.

On Monday, Trump won the Iowa caucuses by approximately 30 points, marking the beginning of the race for the Republican presidential nomination. Following his victory, Trump stated, "We're gonna get the Ukraine war solved."

If elected in 2016, candidate Trump had predicted closer ties with Russia, but those ties never came to fruition.

No reason to doubt U.S. admin support

In his interview with CNBC, Kuleba stated that he has no doubts about the sincerity of the Biden administration's commitment to assisting Ukraine.

I don't believe that the Republican Party as a whole recognizes the importance of defeating Russia in Ukraine and preventing it from further disrupting the world order established by America.

"Let's face it, the world we inhabit was constructed under American leadership," he remarked.

The Biden administration is pushing for more funding from Congress to support Ukraine in its war against Russia, which began in February 2022. The U.S. has been a strong ally of Ukraine throughout the conflict, providing over $75 billion in humanitarian, military, and financial support. However, the latest proposed funding for Ukraine, which could be up to $60 billion, has been stalled in Congress as the Biden administration and House Republicans cannot agree on a broader funding agreement.

This week, Zelenskyy held talks with political leaders and major international investors in Davos, discussing potential aid and investment opportunities. Kuleba, Zelenskyy's advisor, shared with CNBC that Zelenskyy received "encouraging" messages from both political and business leaders during the meetings.

He emphasized that the crucial aspect is for you to sense, perceive, and comprehend the dedication to support Ukraine and continue assisting in any manner possible.

Since last year, Ukraine's counteroffensive has not progressed as expected, and neither side has made significant advancements in the war.
